Dear Nawaz, You are on the right way, you need a Modbus RTU Master package, to save some money you could buy the
Then you need to install the package PtP Param V5.1 incl. SP8(it for free) and you have also to install Modbus Master(also no payment) software to parametize the CP341. If the data isn't that much you could also use a ET200S 1SI module (6ES7138-4DF11-0AB0 USS Serial Interface Module, there you didn't need a copy license, but the data that you could send/receive is less in the same time as for a CP341. But when you have only one slave then that is possible... SeeSerial Interface Module ET 200S 1SIfor more information about the 1SI module for the ET 200S. Also there are some examples for this module: Function Blocks, Examples and User Manuals for the ET200S 1SI Serial Interface |
